-MODULE 1-Introduction

16

Module Objectives

Define work zone strategies

Discuss the need for work zone strategies

Discuss Transportation Management Plans (TMP)

17

Work Zone “Strategies”

An approach for mitigating the impact s of work zones, while ensuring constructability

Must be selected when there are two or more competing interests or alternatives

Strategy: an approach, method, or series of maneuvers for obtaining a specific goal or result

18

Work Zone “Strategies”

Once selected, they are used to develop:

Contract requirements

Transportation Management Plans (TMP)

A Traffic Control Plan (TCP)

All designed to OPTIMIZE the cost and

effectiveness of construction, traffic

management, safety, mobility & social needs.

19

Why do we Need Work Zone Strategies? And Now?

Work zone fatalities remain high

Work zone congestion is worsening

Customer dissatisfaction is high

Work Zone Safety and Mobility Rule requires a Transportation Management Plan (TMP) for all Federal-aid highway projects

20

How do we optimize safety and mobility in work zones?

Analyzing multiple strategies

Advantages and disadvantages

Considering the needs of all the stakeholders

21

Module Recap

How many people die in traffic crashes in the USA every year? In WZ?

When are TMPs required?

What are the 3 components of a TMP? When are all 3 components required?

What are the benefits of TMPs?

-MODULE 2-Temporary

Traffic Control (TTC)

Strategies

23

Module Objectives

Review sources of Federal and State TTC standards and guidelines

Discuss common TTC strategies

24

TTC Strategies are detailed ina Traffic Control Plan

Consistent with the standards and guidelines of the MUTCD, Roadside Design Guide, and applicable documents

25

TTC Strategies Can be Divided Into:

A. Temporary traffic control (TTC)

B. Traffic control devices

C. Contracting & innovative construction strategies

26

Advantages/Disadvantagesof Nighttime Work

Advantages Disadvantages

Lower traffic volumes

Higher agency cost

Lower traffic impacts

Higher speeds; more impaired drivers

Lower impact to commercial activity

Crew social patterns disrupted

Noise and possible compromise of quality

27

C. Contracting Strategies

1. Conventional contract model

2. Alternative contracting techniques

3. Evaluation of contractor designs

28

Module Recap

Which type of warning light is used for delineation?

Name two advantages of nighttime work zones?

Name 2 alternative contracting strategies?

What is lane rental?

29

-MODULE 3-Public

Information & Outreach Strategies

30

Module Objectives

Discuss public information and outreach strategies

Discuss typical steps involved in public information and outreach campaigns

31

Public Information (P.I.) and Outreach Strategies

Communicate wz information:

Road users

The general public

Area residents and businesses

Public entities

Required under the Transportation Management Plan (TMP)

32

P.I. Strategies Considerations

To provide information to stakeholders before the project starts to make them aware of:

The expected work zone impacts and

the State's actions to mitigate these impacts

33

Ways to Communicate Work Zone Information

Maps

Employee newsletters

Video

CB radio network (for truckers)

Billboards

Advertising on buses

Information center or kiosk

34

Module Recap

Why develop and implement a public information and outreach campaign?

Name 3 public information techniques

Which three messages are typically incorporated in wz campaigns?

35

-MODULE 4-Transportation Operation (TO)

Strategies

36

Module Objectives

Discuss TO strategies and their application to work zones

37

TransportationOperation Strategies

A. Intelligent Transportation Systems (ITS)

B. Demand management strategies

C. Corridor/network management strategies

D.Incident management and enforcement strategies

38
